SPECIFICATION forming part of Letters Patent NO. 727,425, dated May 5, 1903.

Application filed June 3, l9 02. Serial No. 1lO ,1 l1. (N0 model.)

To (1% whom, it 177,027 concern:

Be it known that I, LUDWIG VON ORTH, philosophize doctor, a citizen of the German Empire, residing at Ludwigskirchstrasse 9, Berlin WV, Germany, have invented a new and useful Improvement in Devices for Introducing Gases into Bath Fluids, of which the following is a specification.

My invention relates to devices for introducing air and other gases in a finely-divided form into bathing fluids; and the object of my invention is to provide a substitute for baths of that kind where gases are produced in the bath fluid or where fluids which are impregnated with gases are used as bath fluids. I have found that in order to secure a very fine distribution of the gases in the bath fluid it is advisable to press gases through the meshes of a fabric. However, the employment of a fabric covering the bottom of the bathing-tub in one single piece is objectionable by reason of the large surface which is exposed to the gas-pressure.

Now this invention consists in a device for introducing gases in a finely-divided state into the bath fluid by pressing the gas through the meshes of fabric covering longitudinal channels arranged one beside the other on the bottom of the bathing-tub. The longitudinal channels or gas-chambers may have any suitable form and may consist of any suitable material.

In the accompanying drawings I have shown in Figures 1 to 3 in transverse section some forms of longitudinal channels covered with fabric, which may be arranged in a suitable number one beside the other on the bottom of a bathing-tub and connected to a pipe for introducing air, carbonic-acid, or other gases. Fig. 4 shows a plan view of a device consisting of a plurality of longitudinal channels connected to a gas-supply pipe. Fig. 5 isacross-sectional view of Fig. 4.

Referring to the drawings, a represents longitudinal channels of any suitable transverse section. In Fig. 1 the transverse section of the longitudinal channel is that of a trough; in Fig. 2, that of a rectangle; in Fig. 3, that of a circular pipe. The longitudinal channels a are shown in Figs. 1 to 3 as inclosed by layers of fabric 0. Advantageously the fab ric inclosing the longitudinal conduits has the form of a woventube, which is drawn over the channel.

In Figs. 4 and 5 I have shown a plurality of longitudinal channels or pipes a, connected to a principal or primary pipe I), with supply-pipe cl. The pipes are shown as furnished with holes e and embedded in the groovesf of corrugated sheet metal g. The fabric inclosure of the pipes at is not represented in Figs. 4 and 5. However, it is understood that in practice the pipes a are inclosed by one or more layers of fabric, as shown in Figs. 1 to 3.

In order to form a support for the described structure, the same is furnished with a baseplate h, which is of preferably oval shape, approximately that of the shape of the bathtub in which the device is to be placed. The pipes a are also curved or bent so that the pipe structure is of approximately the same shape as the base -plate, above which the pipes are located.

The operation of the device is as follows: The corrugated sheet metal with the pipes o, b embedded in the grooves of same is put into the bathing-tub with the pipes on the upper side. Supply-pipe dis connected to a suitable gas-reservoir. Then the gas enters pipe I) and pipes CL and is pressed through the openings 6 of the pipes a and the meshes of the fabric, so that it enters the bath fluid in form of very small bubbles. The gas-bubbles impregnate the bath fluid and strike the body of-the person resting in the bath fluid above the pipes a. The fabric 0 is preferably formed of vegetable or animal fibers, but, if desired, may consist of Wire-gauze. I have shown the fabric as carried by solid channels a. However,l may dispense with same and introduce the gases directly into woven tubes or the like.

I am aware that prior to my invention perforated pipes or tubes arranged in skeleton form and covered by suitable fabric have been suggested, and I do not, therefore, claim such a structure broadly, but onlyin connection with a device'adapted for introducing gases into bath fluids and which by reason of. the flimsy character of the tubular skeleton structure are provided with a base-plate.

Having now particularly described and ascertained the nature of my invention and in vwalls, layers of suitable fabric inclosing the channels and extending over the openings, means for connecting the channels with a suitable gas-supply and a base-plate upon which the said parts are supported, said baseplate being of the approximate shape of the bath-tub.

3. A device for introducing gases into bath fluids, consisting of a plurality of channels extending longitudinally side by side, and provided with openings in their walls, tubes of fabric drawn over the channels and their openings, means for connecting the channels with a suitable gas-supply and a base-plate upon which the said parts are supported, said base-plate being of the approximate shape of the bath-tub.

4. A device for introducing gases into bath fluid-s, consisting of a plurality of pipes arranged longitudinally side by side and provided with openings, tubes of fabric drawn over the pipes and their openings, means for connecting the pipes with a suitable gassupply and a base-plate upon which the said parts are supported, said base-plate being of the approximate shape of-the bath-tub.

5. A device for introducing gases into bath fluids, consisting of a plurality of fabric-covered channels, the walls of said channels, under said fabric being provided with openings, a primary pipe connected with both ends of said channels and a base-plate upon which the said parts are supported, said base-plate being of the approximate shape of the bathtub.
